Claims. (Cl. 12089) This invention relates to new and useful improvements in a pencil pointer.

It is an object of this invention to provide a pencil pointer for sharpening pencils by the use of sand paper pads, that will permit rotation of the sand paper and will shield the used portion of the sand paper to prevent smudging of the fingers or pencils of the user.

It is another object of the invention to provide a pencil pointer for use by draughtsmen and the like in shaping pencil points that will provide an ample supply of sand paper and that is readily and easily refilled when the supply is exhausted.

It is still another object of the invention to provide a pencil pointer having a body provided with space on the back side thereof for charts, and the like, useful to a draughtsrnan or an artist.

It is still another object of the invention to provide a novel pencil pointer having novel means for main taining a replaceable point cleaner on the body of the pointer.

With the above and other objects in view, the invention has relation to certain novel features of construction and operation more particularly defined in the following specifications and illustrated in the accompanying drawings, wherein:

Figure l is a front elevational view, and

Figure 2 is a side elevational view. I

Referring now more particularly to the drawings, the numeral 1 designates a body member preferably formed of wood or plastic, and which has the handle 2 integral therewith. The body member is round, and in the center thereof is a transverse port in which a suitable axle, such as the externally threaded bolt 3, is mounted. A plurality of discs of abrasive sheets, such as sand paper, or emery paper, which are also provided with a transverse axial bore, are mounted on the bolt 3 and are rotatable thereon.

Discs of sand paper, as 4, are illustrated, however, any type of abrasive sheets may be employed.

A shield, preferably formed of cardboard, as 5, may be formed with an axial transverse bore and of slightly greater diameter than the abrasive discs 4, and mounted on the bolt 3. The shield 5 may be provided with a thurnbpiece 6 to hold the guard-against rotation. A suitable wing nut 7 is mounted on the bolt 3 to maintain the sheets of abrasive 4 and the shield 5 in position on the body member 1.

A point cleaner, preferably formed of felt, as 8, mounted on suitable rigid backing, such as'tin or aluminum, 9, is mounted on the handle 2, there being a pair of outwardly directed grooves cut transversely in the handle on the front face thereof as 10, 10, to receive the downwardly and outwardly directed margins of the backing 9.

When the exposed felt has become saturated with dust or graphite from the pencils being sharpened, the entire cleaner may be slid out of the grooves 10, and a new one mounted on the handle 2.

The shield 5 has a portion cut away, as shown at 11, in Figure 1, exposing a portion of the abrasive sheet 4. The user will hold the shield against rotation, when the exposed portion of the abrasive sheet has become used, and the disc 4 rotated, passing the used portion of the disc beneath the shield 5 and exposing a clean portion of the disc for use. When a disk has been entirely used, the wing nut may be removed and the disc lifted off of the bolt 3 and the shield then replaced and the wing nut again mounted on the bolt 3 and a clean disc will be ready for use. When the supply of discs is exhausted, a new supply may be readily and easily mounted on the bolt 3.

A suitable hanging orifice as 12 may be provided if desired.

The shield 5 may be cardboard, and thus disposable, so that it may be replaced with each new supply of discs, or it may be of plastic, and easily cleansed by the user when necessary.

While the foregoing is considered a preferred form of the invention, it is by way of illustration only, the broad principle of the invention being defined by the appended claims.

What I claim is:

1. In a pencil pointer, a round body member, a handle integral therewith, an axial port in said body member, and a bolt mounted in said port and extending laterally therefrom, a series of abrasive discs mounted on said bolt and a shield mounted on said bolt and covering the faces of said discs, a portion of said shield being cut away to expose a portion of the surface of the topmost disc.

2. In a pencil pointer, a body member, a handle integral therewith, a bolt mounted in the center of said body member forming an axle, abrasive discs mounted on said bolt and rotatable thereon, a shield mounted on said bolt and means for maintaining said discs and shield on said bolt.

3. In a pencil pointer, a body member, a handle integral therewith, a bolt mounted in the center of said body member forming an axle, abrasive discs mounted on said bolt and rotatable thereon, a shield mounted on said bolt covering said discs, said shield having a portion cut away exposing a portion of said discs, and a means on said shield for holding same against rotation.

4. In a pencil pointer, a body member, a handle integral therewith, a bolt mounted in the center of said body member forming an axle, abrasive discs mounted on said bolt and rotatable thereon, a shield mounted on said bolt and means for maintaining said shield and discs on said bolt, a pair of transverse grooves in said handle and a point cleaner mounted in said grooves.

5. In a pencil pointer, a body member, a handle on said body member, an axle mounted in the center of and extending laterally from said body member, abrasive discs rotatably mounted on said axle, a shield partially covering said discs and a point cleaner having rigid backing and an absorbent face detachably mounted on said handle.
